PNEUMATIC- TIRE GUARD.

SPECIFICATION forming part of Letters PatentrNo. 771,190, datedSeptember 27, 1904.

Appncaiion nea Juiy 17, 190s.

To all whom, it may concern.'

Be it known that I, LAURENT VANDERPERRE- SIMON, a subject of the KingIof the Belgians, and a resident of Brussels, Belgium, have inventedcertain new and useful Improvements in Imperforable Guards to Adjust toPneumatic Tires on Automobiles or other Vehicles, of which the followingis a specification.

My invention pertains to pneumatic tires; and the object is to provide aguard for the same, so that the tube cannot be perforated or ruptured.

It consists of an ordinary rubber or iieXible tire having an interiorrubber tube, the tread ofthe outer rubber 1tube being thickened orreinforced in the usual way, and between the two tubes alongthe`tread'portion I place a series of metal plates or blades, which areinclosed or held together by atissue of fiber, composed of horsehair orother material, which are secured in position by means of rivets orbolts having projecting heads, made, preferably, cross-shaped, which aredesigned to travel on the ground, and thus relieve the surface of thetire from wear as well as to prevent slipping of the same, as will nowbe set forth in detail.

ln the drawings, Figure 1 is an edge view of the metallic plate used inthe tire. Fig. 2 is a top or plan view of a series of such plates; Fig.3, a cross-section of the metallic plates, secured in a tissue of iber;Fig. 4, a cross-section of one of the securing bolts or rivets; Fig. 5,a top view of the head or bearing' end of the rivet or bolt; Fig. 6, across-section of a tire, showing manner of applying the improvementthereto; and Fig. 7, a view of portion of a tire.

In constructing my invention I provide a tire 8, made in the ordinaryway and secured to a rim 9, the base portion l1 being slitted, as shownat 10, by means of which it may be attached to the rim. An inner tire 12is 'also employed, with suitable means for inflating same. (Not shown.)

The principal features of my invention consist of a series oftransversely-disposed blades 13, made of wood, bone, horn, whalebone, orother suitable material, which are incased be- Serial No. 165,988. (Nomodel.)

l tween webs 14, of horsehair, fiber, or metal, and held together inproper relation with each other by means of rivets 15, the tissue thusformed being placed between the inner airtube and the outer tire, bentto conform with the shape of the tire and tube. This tissue is securedto the tire by means of bolts 16 at suitable intervals.' Each bolt has ahead 17, which rests against the inner surface of the tire and projectsout a suitable distance to receive a peculiarly-formed bearing-plate 18,through which the bolt passes, and is secured b v means of a nut 19, orthe nut may be riveted. The opening in the bearing-plate is countersunkand adapted to receive a softmetal washer 20, which iits in thecountersunk socket, whereby a tight joint may be made, and to furthergive security I use a washer 2l to receive the nut 19 or the riveted endof the bolt. The outer surface of the bearing-plate may be provided withcross-ribs 22 or have other suitable raised surfaces which strike thesurface of the ground and serve to prevent slipping of the tire.

What I claim as new is- 1. A pneumatic tire having an air-tube and aprotecting tissue between said tire and tube, with projectingbearing-plates secured to the outer tube and to said protecting tissue.

2. In a pneumatic tire, the combination of a tire, an air-tube, aprotecting tissue between them and a bearing-plate at intervals on theouter surface of the tire secured to the tire and tissue by bolts, asset forth.

3. In a pneumatic tire, the combination of a tire and an air-tube,having between them a tissue composed of transverse plates or strips ofwood, bone or other material incased in fibrous metallic Webs, andbearing-plates in the outer surface of said tire secured to said tissueand web by bolts, substantially as set forth.
